Mechanical knowledge: the principle of self-lubricating bearings

Self-lubricating bearings
Currently various machinery industry is still used in most of the ball bearings, needle roller and the like, has been used only a small part of the self-lubricating bearings, we believe that in the near future will come from lubricating bearings sliding adaptability, wear-resistant, self-lubricating bearings and other economic indisputable advantage to become the bearing industry leading products. Here are some application features and advantages of the self-lubricating bearings: non-oil lubricated bearings
1, or less non-oil lubrication oil lubrication apply to the oil-free sliding bearings or oil fuel is difficult to place, it can be used without maintenance or less maintenance.
2, wear resistance, low coefficient of friction, long service life. 3, there is the right amount of plasticity, can stress distribution in a wide contact surface, increase the carrying capacity of the bearing.
4, static and dynamic friction coefficients are similar, can eliminate the oil-bearing bush crawling at low speed, thus ensuring the accuracy of machine operation.
5, make the machinery to reduce vibration, reduce noise, prevent pollution and improve working conditions.
6, during operation, can form a lubricating film, played the role of protecting the shaft, no bite-axis phenomenon.
7, for grinding axes low hardness without quenching of the shaft can be used, thereby reducing the associated parts of the process difficult.
8, thin-walled structure, light weight, can reduce the machine size.
9, a variety of metal plated steel back can be used in corrosive media; has been widely used in various mechanical sliding parts, such as: printing presses, textile machines, tobacco machines, micro-motors, automobiles, motorcycles and forestry machinery and many more.
Boundary lubrication self-lubricating bearings series introduced
1. The carrier is good, good wear resistance.
2. Suitable for high load low speed rotary motion, oscillating motion and frequent opening and closing under load frequent and difficult to form hydrodynamic lubrication occasions.
3. In the long term under boundary lubrication conditions without refueling and maintenance, and refueling in the bearing layer over a longer service life.
4. The surface of the plastic layer at the time of molding can be left a certain margin, holing hole mounting pressure after self-processing, in order to achieve better assembly size.
5. The products are mainly used in auto chassis, metallurgical machinery, mining machinery, irrigation machinery, construction machinery, agricultural machinery, steel rolling equipment. JDB solid mosaic bearing series JDB solid mosaic bearing series is the common infrastructure products, regardless of high pressure, low pressure, high temperature, low temperature, oil-lubricated, non-lubricated or water lubricated, can adapt. Product matrix is ​​a high-strength brass, copper sleeve than double the hardness, wear resistance more than double. Widely used: light industrial machinery, heavy machinery, construction machinery, metallurgical machinery, transport machinery, such as: continuous casting machines, rolling mills, injection molding machine, paper machine, mold guide column, ships, machine tools and so on.
